To all IF/(H1, it 'Illllf/ concern.

lie it known that I, EDGAR D. MIsNER, a citizen of the United States,resldln at Detroit, in the county of \Vaync and i tatc of Michigan, haveinvented new and useful e. The invention has for one of its objects theprovision of means which, is rotatable in opposite directions topredetermined positions to move one of the rolls of the wringer towardthe other and to hold this movable roll under different tension; andalso the provision of a cam member having inclined faces terminating inoff-set steps for cooperating with the rotatable tensioning member tomove the movable roll of the wringer toward the other upon rotation ofthe tensioning member and to hold the same in either of its adjustedpositions. The invention has for another object, the provision ofequalizing means for facilitating the I simultaneous and equalmovementsof the opposite ends of the movable roll when moving away fromthe other roll. Further ob jeets of the invention reside in the novelfeatures .of construction as more fully hereinafter set forth.

In the drawin Fig. 1 is a si e elevation partly broken away and insection, of a wringer embodying my invention.

Fig. 2 is a top plan view thereof; Fig. 3 is a cross section on the line3-3 of Fig. 1;

Fig. 4 is a bottom plan view of the stepped cam member;

- Fig. 5 is a cross section on the line 5-5 of Fig. 2.

l is the frame of the wringer formed of the complementary sections 2 and3 which are suitably secured to each other as by means of the machinescrews 4. 5 is the power driven roll and 6 the cooperating roll. Theshaft 7 of the power driven roll is rotatably mounted in hearing blocks8 at its oppositeends which are positioned between the complementarysections 2 and 3. 9 is a gear secured to one end of the shaft 7 andadapted to mesh with the gear 10 secured to the corresponding end of theshaft 11 of the coo eratin roll, these two gears being inclose withinthe enlargement 12 formed upon the complementary sections 2 and 3.13-are bearing blocks located at the opposite ends of the shaft 11 andslidably engaging between the complementary sections 2 and 3 of theframe.

The bearing blocks 8 and 13 are preferably formed of wood-andimpregnated with lubricant, each having the half bearing 14 forengagement with the shafts.

15 is a resilient bowed member extending abovethe cooperating roll 6 andhaving its ends engaging in rectangular apertures 16 in the upper end ofthe metal strips 17 which are at the inner sides of the bearing blocks13 :md have circular openings 18 near their lower ends for engagementwith the shaft 11, these circular apertures being of sufficient diameterso that when the cooperating roll 6 is moved toward the power drivenroll 5 by means of the ends. of .the resilient bowed member contactingwith the tops of the hearing blocks 13, the shaft-11 will contact withthe half bearings in the bearing blocks 13. 19 is a tensioning rodextending transversely of the resilient bowed member15 andlongitudinally movable in the cam member 20 secured centrally to the topof the frame 1. This tensioning rod is secured at its lower end to theclip 21 by means of the screw 22 threadedly engaging the clip andextending into the annular groove 23 in the tensioning rod. The lowerportion of the clip is U- shaped to embrace the center of the resilientbowed member 15.

Forthe purpose of facilitating the movement of the cooperating roll 6toward the power driven roll 5, the cam member 20 has the pairs of camor inclined faces 24 and 25 at the lower ends of which are the shouldersor steps 26 and 27 respectively, and the tensioning rod 19 has thetransverse projection 28'. which is preferably a pin, extending out fromone side thereof for engagement with these inclined faces and steps, theparticular face and step being dependent upon the direction of therotation of the tensioning rod. The transverse pin 28 is normallybetween the upper ends of the inclined faces when there is no tensionupon the resilient bowed member 15 so that this pin is in position toengage the inclined bowed member when the transverse pin is in from itsengaged step;

en agement with each ofthese steps.

0 release the pressure of the cooperating roll upon the power drivenroll it is merely necessary to rotate the tensioning rod 19 to disen ageits transverse pin 28 from its engage step, when the pin will ride upover an inclined face. The flat steps 26 and 27 on either side make thereleasing movement in either direction similar. The handle 29 isprovided at the up er end of the tensioning rod for rotating t e same tomove the cooperating roll 6 toward the power driven roll or fordisengaging the transverse pin and to prevent r0- tation of this handleupon releasing the pressure, and after the transverse pin 28 has movedover an inclined face, the upper portion of the cam member 20 has thediametrically opposite slots 30, the walls of which connect into theupper ends of the inclined faces. The handle extending each side of thetensioning rod is conveniently located to permit it to be instantlyactuated by the operator in case of accident as for instance thecatching of a hand in the rolls and the sli ht circumferential extent ofthe steps 26 an 27 make a very short turn necessary to affect a release.

To facilitate the simultaneous and equal movements of the opposite endsof the cooperating roll 6 when moving away from the power driven roll 5,the lower end of the tensioning rod 19 has the recess 31 to receive thecoil spring 32. When the tensioning rod is in either of its innermostpositions to tension the resilient bowed member 15, the latter restsagainst the lower end of the tensioning rod; but when the mechanism istripped, the spring 32 will clamp the resilient bowed member against thebase 33 of the U-shaped portion of the clip 21, which base forms anextended bearing for the resilient bowed member and thereby preventsrocking movement of the resilient bowed member relative to thetensioning rod. This resilient bowed member is preferably formed withthe lug 34 which is engageable within the lower convolution of the coilspring 32 to longitudinally position the resilient bowed member; Thebearing blocks 13 also preferably have their sides slightly tapering toavoid too great a frictional resistance to their movements.

To limit the upward movement of the cooperating roll 6 when themechanism is tripped, the complementary sections 2 and 3 engaged by anywater which drops off the ends of the 1 1o ls of the wringer frame arespaced apart a distance less than the diameter of the cooperating rolland have the transversely" extending flanges .35 which an adapted to bethe cooperating roll. To drain inwardly away from the ends of thewranger frame, there are inwardly extending and downwardly inclinedflanges 36 beneath the power driven roll.
